ABSTRACT:
A multi-port (multiplexed) modem for implementing automatic reconfiguration of the ports so that transmission bandwidth can be optimized. The modem utilizes a sequence of communications and acknowledgments transmitted over the donor port donating the bandwidth and the recipient port receiving the bandwidth. This allows reconfiguration of the modem ports without need for interruption of the unaffected ports and requires no secondary channel to implement. Only the port going idle and the port receiving the bandwidth are affected so that communication channel throughput is maximized and unaffected ports are not interrupted.
